The expert system are given inputs such as questions, locations and information. The expert system processes and advice the user on what to do. If the user inputs the location of an oil site and ask a question if they are able to drill an oil out of the site, then the expert system calculates and gives you the answer you need. Though the expert system makes errors just like humans.
Answer:
integer
Explanation:
The expression can be implemented as follows:
x <- 4L
class(x)
Here x is the object. When this expression is executed in R, the class "integer" of object 'x' is determined by the class() function. R objects for example x in this example have a class attribute determines the names of the classes from which the object inherits. The output of the above expression is:
"integer"
Here function class prints the vector of names of class i.e. integer that x inherits from. In order to declare an integer, L suffix is appended to it. Basically integer is a subset of numeric. If L suffix is not appended then x<-4 gives the output "numeric". Integers in R are identified by the suffix L while all other numbers are of class numeric independent of their value.
Answer:
import math
tolerance=0.00001
approximation=1.0
x = float(input("Enter a positive number: "))
def newton(number,approximation):
approximation=(approximation+number/approximation)/2
difference_value =abs(number-approximation**2)
if difference_value<= tolerance:
return approximation
else:
return newton(number,approximation)
print("The approximation of program = ", newton(x, approximation))
print("The approximation of Python = ", math.sqrt(x))
Explanation:
- Create a recursive function called newton that calls itself again and again to approximate square root for the newton technique.
- Apply the formulas to find the estimate value and the difference value
.
- Check whether the difference_value is less than the tolerance value and then return the value of approximation else make a recursive call to the newton function by passing the user input and the new approximation value
.
- Finally display all the results using the print statement.
Answer:
Single-evidence form
Explanation:
Single-evidence form dedicates a page for each item retrieved for a case; it allows investigators to add more detail about exactly what was done to the evidence each time it was taken from the storage locker.
